CARPET SWEEPER AND BEATER.

SPECIFICATION forming part of Letters Patent No. 738,019, dated September 1, 1903.

Application filed March 16, 1903. Serial No. 148.016. (No model-l To all whom, it may concern:

Be it known that 1, ANDREW V. FnnoR, a citizen of the United States, residing at W'ilkesbarre, in the county of Luzerne, State of Pennsylvania, have invented certain new and useful Improvements in Carpet- Sweepers and Beaters, of which the following is a specification.

This invention relates to improvements in combined carpet sweepers and heaters, and is illustrated in the accompanying drawings, in which- Figure l is a vertical sectional view through a carpet sweeper and beater constructed in accordance with this invention. Fig. 2 is a plan view,the top of the casing being removed. Fig. 3 is a detail view on an enlarged scale.

Referring to the drawings, 1 designates the casing of a carpet-sweeper, which may be'of any desired form and within which is mounted a horizontal brush, the shaft 2 of which is adapted to be rotated by suitable gearing as the sweeper is moved over a carpet. In advance of the brush I arrange a series of heaters 3, each of which is pivotally supported at its forward end to rock about an axis parallel to that of the brush. The rear end of each beater is normally held in a depressed position by means of a suitable spring, and each heater is provided with a rearwardly-extending arm that extends into the path of and is adapted to be moved vertically by suitable tappets on the brush-shaftZ. In the embodiment of the invention illustrated in the drawings each beater consists of three parallel rods, which may be formed of suitably heavy wire, said rods being connected at their forward and rear ends in any preferred manner. As shown, the forward ends of the rods are connected to one member or leaf of a hinge 4, the other member of which is secured to the inner face of the front wall of the casing 1. The rear ends of the members of the beater are bent upwardly, and from said upward rear end projects rearwardly an arm 5. This arm is curved or bowed at its upper end to pass over the shaft 6, upon which the forward supporting and driving wheels of the sweeper are secured, and the rear end of said arm 5 is inclined downwardly and rearwardly from said shaft. To the rear end of the beater is connected one end of a bowed or curved leafspring 7, the other end of which is attached to the lower face of the top of the casing 1. The spring 7 acts to normally depress the rear end of the heater and force the same against the surface over which the sweeper is moving.

Referring to the drawings, it will be seen that the bristles of the brush are arranged in a series of longitudinally-separated groups, four of such groups being illustrated in the drawings. Within the spaces between said groups are pivotally mounted a series of tappets 8, which as the brush revolves will suecessively engage the rear ends of the arms 5 of the heaters, said arms projecting rear-- wardly from the heaters in alinement with said spaces between the groups of bristles. The tappets S are preferably made in the form shown, each having a bifurcated enlarged inner end which receives and is pivotally connected to an eye 10, attached to the shaft 2. The tappets are of such form and so mounted that when the sweeper is pushed forward the bifurcated endst) will be forced into close contact with the shaft 2 as the outer ends of the tappets come into engagement with the arms 5, and said arms will thereby be melted upwardly. WVhen the sweeper is moved in the opposite direction, or rearwardly,

the tappets will offer no obstruction to the.

rearward rotation of the brush, but will lie close against the shaft 2. Whenthe sweeper is moved forward, the tappets fall by gravity into proper position for engaging the arms of the boaters. To prevent the bristles of the brush adjacent the spaces in which the tappets are arranged from being displaced laterally and interfering with the action of said tappets, guards 11 are provided. These, as shown, are formed of wire bent to have a body portion extending substantially concentrio with the shaft2 and having the ends thereof bent inwardly and suitably attached to said shaft.

A shield 12 is preferably arranged in advance of the wheelshaft 6, and suitable notches are formed therein, into which the arms 5 can extend when the heaters are depressed by' their springs 7. An elastic cushion-strip 13 may be arranged against the inner face of the top of the casing 1 above the springs 7 to prevent said springs striking said top when in action and producing an objectionable noise.

The brush-shaft may be rotated by any suitable gearing. In the form of the invention illustrated in the drawings said shaft is provided at its ends with driving-disks, which are frictionally engaged and rotated by wheels 14, mounted on the ends of the aforesaid shaft 6 and a corresponding shaft journaled in the case in rear of the brush, said wheels supporting the casing. A bail 15 is pivotally connected to opposite sides of the casing and provided at its middle with a socket 16, into which a suitable handle may be inserted in the ordinary manner, by means of which the sweeper may be moved over the carpet to be cleaned.

The operation of the invention will be evident from the foregoing description and the drawings. As the sweeperis moved forward and the brush rotated the heaters arranged in advance of the brush will be oscillated and caused to strike the carpet with considerable force, thereby separating the dust and dirt contained therein from the body of the carpet and allowing the brush to sweep the same into the receptacle provided in advance of thebrush. Asimilarreceptacle17isprovided in rear of the brush.

Anysuitable number of heaters may be employed. In the form of the invention illustrated in the drawings three are shown. It will be noticed that each heater is independently mounted and the tappets on the brushshaft are so arranged that the heaters are successively operated, so that while the sweeper is advancing the carpet will receive a practically continuous beating.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

1. The combination with a carpet-sweeper having a rotary brush, of a heater arranged in advance of the sweeper-brush, and means on the shaft of said brush for actuating the beater as the brush rotates.

2. The combination with a carpet-sweeper having a rotary brush, of a heater arranged in advance of the sweeper-brush and having its forward end pivotally connected to the sweeper-casing, a spring engaging the rear end of the heater and acting to depress said end, and means on the brush-shaft forperiodically raising said rear end of the beater against the action of the spring as the brush revolves.

3. The combination with a carpet-sweeper having a rotary brush, of a beater pivotally connected to the sweeper-casing in front of the brush, a rearwardly-extending arm connected to the heater, and a tappet on the brush-shaft adapted to engage said arm and actuate the beater as the brush rotates.

4. The combination with a carpet-sweeper having a rotary brush, of a beater consisting of a plurality of arms connected at their forward ends by aplate that is hinged to the sweeper-casing in front of the brush, a spring connected to said heater and acting to depress the rear end thereof, a tappet mounted on the brush-shaft, and an arm connected to the heater and extending rearwardly therefrom into the path of said tappet, whereby as the brush-shaft revolves the beater will be periodically raised against the action of said spring.

5. In a carpet sweeper and heater the combination of a suitable casing, a horizontal brush journalecl in hearings in the casing and having its bristles arranged in separated groups, means for rotating the brush as the sweeper is moved over a carpet, a heater arranged in front of the brush and havinga rearwardly-extending arm in alinement with a space between groups of bristles of the brush, and tappets pivotally mounted on the brush-shaft and adapted to engage said arm and actuate the beater as the brush rotates.

6. In acarpet sweeper and heater, the combination of a suitable casing, a brush, means for rotating the brush as the casing is moved over a carpet, a heater arranged in front of the brush and having a rearwardly-extending arm, tappets secured to the brush-shaft and adapted to engage said arm and actuate the beater as the brush rotates, and guards on the brush-shaft for preventing the adjacent bristles from spreading laterally into the path of said tappets. 1

In testimony whereof I aflix my signature in presence of two witnesses.

ANDREIV V. FEDOR.
